Omar has a perfect mix of exoticism and familiarity, with the additional plus of a strong, open initial O. Commonly used among Muslim families, Omar was long associated with twelfth century Persian poet Omar Khayyam, though it sounds anything but ancient now.
More recent well known bearers have been World War II General Omar Bradley and actors Omar Sharif(born Michael) and Omar Epps.
Omar is also mentioned in the Old Testament book of Genesis. It was in the US Top 200 from 1976 through 2012, but landed just outside at Number 217 in 2015 and Number 223 in 2016.
